Google contracts 3,590 MW of nuclear power from Constellation Energy to supply its PJM‑grid data centers
Executive summary: Google signed a contract to obtain 3,590 MW of nuclear power from Constellation Energy, with delivery via the PJM Interconnection grid. The agreement secures a substantial, low‑carbon electricity source for Google’s energy‑intensive data centers, underscoring how major tech firms are turning to nuclear to meet climate targets and AI‑driven power needs.
Who is involved: Google/Alphabet, Constellation Energy, and the PJM Interconnection (grid operator).
Likely next (inference): Google will begin integrating the contracted power into its data center operations; Constellation may advance related nuclear projects; regulators may review the grid impact under PJM market rules.
Google/Alphabet has announced a power purchase agreement with Constellation Energy for 3,590 megawatts of nuclear electricity, to be delivered through the PJM Interconnection grid that serves 67 million people across 13 states and Washington, D.C. The deal represents one of the largest corporate procurements of nuclear power in the United States and is aimed at meeting the growing energy demand of Google’s data centers, particularly those supporting AI workloads. By locking in a long‑term supply of low‑carbon electricity, Google seeks to advance its sustainability goals while potentially influencing market dynamics for nuclear generation in the PJM region.
What's next — scenarios
Inference: scenarios and probabilities are Beyond's assessment, not reported fact.
Base: Power delivered as scheduled (70%)
Google uses the contracted nuclear electricity to power its data centers, lowering its carbon intensity and stabilizing energy costs.
- Google announces that the contracted power is being delivered to its facilities
- Constellation reports progress on nuclear plant outages or upgrades
Upside: Additional clean‑energy contracts follow (20%)
Google signs further renewable or nuclear PPAs, increasing its clean‑energy share beyond the current 3,590 MW.
- Google discloses new power purchase agreements in quarterly filings
- Constellation secures additional nuclear capacity allocations
Downside: Delivery delays or regulatory setbacks (10%)
Delays in nuclear plant completion or PJM market rule changes reduce the actual power supplied, forcing Google to rely on alternative sources.
- Regulators issue a notice delaying nuclear plant licensing
- PJM files a market rule change affecting large‑scale PPAs
